    • RE: Yamaha DTR 125 CDI unit Questions

      Right need some help please

      Is there any way to find out if the 3rm-20 Cdi unit is okay?

      the problem im having

      Turn the bike on the power valve will turn to normal position but it dose not do the forward backwards cleaning cycle/movement when it turns on. It's the 5 wire power valve 2 wires go to the internal motor (black and red) (black and brown) and 3 wires (yellow and blue) (white and black) (white and red) go to the veriable risistor inside the power valve which is 7.5k ohms resistor

      dose anybody know what the voltages out of the cdi unit should be while the bikes ignition is on for the powervalve side

      any help greatly appriciated
